Colleen may have returned to The Young and the Restless this week, but that doesn't mean Tammin Sursok's stay on the show will be a long one.

In fact, sources have confirmed to Daytime Confidential that the actress has been fired.

"Tammin has been let go from The Young and the Restless," said an insider. "She's been really busy with a lot of other projects, so it's been hard for the soap to write her in."
